Yay.  I just tried the new MobileMe Calendar, and I can sent calendar invites to my office email (because not syncing with my iPhone), accept the calendar invite on the office calendar, and now the office and MobileMe calendar match up.  What a time saver, no more having to make double entries on two difference calendars.  What a time saver.  Thanks Apple!  (PS, Apple does have a download for a PC to sync MobileMe with an outlook calendar, but again, if your office does not authorize downloads, that option is not available, and this method of iniviting the office you to the mobileme calendar is a workaround.)
